| Tune
and Tune Plane |
|
|
| We
define the “tune” Q (or n) as the number of complete betatron oscillations around the |
|
| ring. |
|
| For example,
the horizontal tune of the Booster is about: |
| 6.7 |
| Beam
Stability |
| Magnet Count/Aperture optimization |
| In general… |
| “small”
integers |
|
|
|
|
|
| Many
deviations from the ideal lattice are |
||||
| characterized
in terms of their resulting |
||||
| “tune-shift”. In general,
the beam will |
||||
| become
unstable if it
shifts onto a |
||||
| resonance. |
